Russian drones have struck Ukrainian mobile carrier Kyivstar's headquarters in Kyiv over the weekend, as data centers in the country have also been targeted.

Kyivstar confirmed the attack to Interfax Ukraine news agency, reporting no injuries or casualties.

It's the third time this month that Kyivstar, Ukraine's largest mobile carrier, has been targeted by Russia.

The first time was on September 11, when a Russian drone attack struck a Kyivstar office in the capital. This was followed up by a second incident, when another Kyivstar building in Kyiv was attacked.

As previously reported by DCD back in 2023, the country's telecoms operators have faced ongoing challenges of rebuilding their respective mobile networks amid the country's ongoing war with Russia.

However, it hasn't just been Kyivstar that has seen its infrastructure attacked this week, as Vodafone Ukraine's facility has also been targeted.

Reuters reported that one of Vodafone's data centers was attacked over the weekend, while TASS noted that another telco, Ukrtelecom, also saw one of its data centers attacked.

Vodafone hasn't publicly commented on the attack as of yet, though the company hasn't been the only one to see its data center infrastructure targeted.

Earlier this month, Russia claimed responsibility for an attack on the De Novo data center in Kyiv, Ukraine, one of the country’s largest data centers.

"Russia has targeted major Ukrainian ​data ⁠centers, seeking to disrupt the flow of information. Rapid alerts about missile and drone ⁠threats are ​essential - they save lives," ​said Andrii Sybiha, Ukraine's foreign minister, on X last week.

Russia's Ministry of Defense (MOD) confirmed that the country has been targeting Ukraine's communications and logistics centers, as well as naval vessels, in a Telegram post.

In the post, the MOD confirmed it had hit the Vodafone data center, plus Omega Telecom, which has since said that all its equipment at its main technical hub was destroyed during Russia's strike on Kyiv.

Another data center operator, Cosmonova, confirmed that its data center in Kyiv will "no longer be operational" after being destroyed in the strikes.

"Despite the scale of the damage, we continue to work on localizing the consequences of the damage, partial transfer, and restoration of services. We will provide details about the client equipment that was located in the data center as soon as possible. Currently, access to the DC is partially limited by the relevant services, even for DC|Cosmonova specialists," said the company.

The current conflict in Ukraine began on February 24, 2022, when Russia launched a military invasion of the country. Since the conflict broke out, there have been an estimated 400,000 to 2 million casualties - killed and wounded - as of June 2026.

This year so far, the Ukrainian guerrilla group Atesh has also attacked communications infrastructure in Russia, including in the Kherson region and Belgorod.

Earlier this year, Ukrainian forces struck a Russian data center facility in Russian-occupied Prymorsk, in the Zaporizhzhia Oblast, Ukraine.

It was also reported last week that neighboring Poland has seen infrastructure quietly attacked, including a fire at a Starlink satellite station. A Polish government minister labeled the fire as a deliberate "act of sabotage."

The fire in the Masovian Voivodeship province was "deliberately designed to disable the station... disrupting internet access for various institutions, including the Ukrainian army," said Krzysztof Gawkowski, Polish Deputy Prime Minister, per the BBC.
